Disk Utility Error Invalid fsroot and apfs_num_other_fsobejcts
Running Disk Utility FIrst Aid on the Macintosh Hd Volume has following error :-
warning: apfs_num_other_fsobjects (60) is not valid (62)
The whole Detail as appeared in mac is as follows:-
Running First Aid on “Macintosh HD” (disk1s1) NOTE: First Aid will temporarily lock the startup volume. Verifying file system. Volume could not be unmounted. Using live mode. Performing fsck_apfs -n -l -x /dev/rdisk1s1 Checking the container superblock. Checking the EFI jumpstart record. Checking the space manager. Checking the space manager free queue trees.

i had searched internet but i can’t find any solution to this error.
Also i had done 1 step before coming to this as i was getting error :fsroot tree is invalid
Following is the message which appeared on running first aid:-
NOTE: First Aid will temporarily lock the startup volume.

So in order to solve i had first of all Boooted in Recovery Mode and then Run first aid on Mac HD Volume.
After that the error was removed.
And when i came back to normal boot and run first aid i got the error (as mentioned above) : apfs_num .
So i went on to try my best be searching on web but i could not find anything else. And then i tried 2nd thing from Single User mode. (CMD S on boot) .
- Start up Mac in single-user mode by restarting then press and hold Command + S.
- Type /sbin/fsck -fy into the command line and press Enter. This will initiate a file system check. You will see the same error, however in this case the repair will continue and fix the issue.
- Type reboot and press Enter.
- Login as normal and run First Aid on Disk and the error should be gone.
Still this did not solve the APFS error. :-
warning: apfs_num_other_fsobjects (60) is not valid (62) .

Also that i have tried Stellar Recovery software and i found that because of these errors, recovering files from macbook is not possible. I am Using Mojave 10.14.6 as of now. The Stellar website suggests to go for complete reformatting Macintosh HD which by the way means to reformat my mac.
Here is the link to Stellar's Post:-
Please find a solution as because of this i can not recovery my files through any recovery software as APFS is problematic.
Also that i don’t think reformating is an option i can go for as i being. a music producer i have got VSTs (music softwares )on my mac and this would mean long hours of backup and then reinstallation on formatted mac. It is highly unproductive to reformat . Please find a a proper solution for APFS Drives.
